1. A method of rerouting flow through the small intestine of a patient with an implanted artificial sphincter that encircles a portion of the small intestine, wherein the small intestine includes a duodenum, a jejunum extending from the duodenum, and an ileum extending from the jejunum, the method comprising:
(a) providing the artificial sphincter in an open state to thereby permit intestinal flow through the encircled portion of the small intestine such that the intestinal flow passes through the duodenum, the jejunum, and the ileum; and
(b) in response to a first user-activated electrical input, transitioning the artificial sphincter to a closed state to constrict the encircled portion of the small intestine and thereby redirect intestinal flow from a first portion of the small intestine to a second portion of the small intestine such that the intestinal flow bypasses at least a portion of the jejunum,
wherein the artificial sphincter comprises an actuator and a constricting member coupled with the actuator, wherein transitioning the artificial sphincter to the closed state comprises actuating the constricting member with the actuator to constrict the encircled portion of the small intestine.
